In this paper, important agricultural applications are highlighted, and applicability of IoT towards improved performance and productivity are discussed. Characteristics of IoT are presented. Usable hard ware platforms, wireless communication technology standards, and IoT cloud services for agricultural applications are analyzed. Various sensor based IoT systems also listed in this paper. Author also reviewed and studied the existing IoT deployments in multiple domains. IoT sensors may provide information about agriculture fields and then act on it based on user input. The development of a system that can monitor temperature, level of water, wetness, and even movement if any occurs in the field that may kill the crops in an agricultural field using sensors utilizing the Arduino UNO board is termed as smart agriculture. The goal is to integrate developing technologies, such as the Internet of Things (IoT) and smart agriculture with automation. After the hardware has been built to meet changing needs and technologies, the software must be updated. The modified hardware is referred to as a new software version. This new version must be checked to ensure that the modifications are correct. It also won't introduce faults in other parts of the software. This is required because changing one component of the hardware can have unintended consequences in other parts of the hardware. Key Words: Internet of things(IOT), Smart Agriculture using IOT, Arduino, Soil Moisture Sensor, Water Level Sensor. 1. INTRODUCTION The Internet of Things (IoT) is expanding, growing, and getting more popular by the day. In today's world, approximately 5 billion things are connected to the internet. Around 50 billion things are expected to be connected to the internet by 2020, according to estimates. IoT is opening up a world of possibilities for new applications, which are now being employed in a variety of areas, including intelligent home monitoring systems, product supply chain management, precision agriculture, and much more. Using RFID (Radio Frequency Identification), Wireless Sensor Network (WSN), or other methods, everything in the Internet of Things is reachable, recognized, readable, and locatable over the internet. Precision agriculture, product supply chain management, Smart Grid, environmental monitoring, cloud computing, and other sectors are all using the Internet of Things concept. IoT is gaining much importance these days as every object in the network will become a computer. The idea of IoT has become successful due to the invention of recent technologies like sensors, RFID and WSN.

GPS, soil scanning, data management, and Internet of things technologies are available to farmers in the twenty-first century. The purpose of smart agriculture research is to develop a farm management decision-making assistance system. From crop planting and watering to health and harvesting, smart farming considers it important to address the concerns of population expansion, climate change, and labour, all of which have received a lot of technological attention. A system is constructed for monitoring the agricultural field with the help of sensors (light, humidity, temperature, soil moisture, etc.) and automating irrigation in IOT-based smart agriculture.
